Hi, I have the same issue with Tablet Samsung Galaxy Note 10.1 2014 edition.

It says that there is an unknown problem and I should contact the support.

I already reinstalled the app on my device. I also deleted the devices in my security tab. I am on a Basic subscription.

Any fix?

Hey Pimpf, thanks for posting your question here, and sorry to hear that you're having trouble with this. 

Just to make sure that we cover as much initial troubleshooting as possible, could you clarify if you're on a Basic account by going to your Plan tab and also checking if you have more than three devices already linked on your Security tab?

Looking forward to hearing back from you!

OK. I checked again: I am on a BASIC subscription.

I only have one device linked which is my Android Tablet. Still I get the message "unknown error. please contact support"

If I delete the Android tablet from the list (to connect it again) I get the same error.

The Tablet will show up as linked device. But I can not log in via the app on my tablet.

Thanks for following up. I fixed it by deleting the account for the very phone that I was trying to link with, then reconnecting this phone using my only remaining account. All fine now

Thanks for checking that for me, confoodnet. I moved your thread here, where other users have expressed similar concerns. 

As Daphne also mentions, our team is aware of the issue and are currently looking into this. As soon as I have any news or updates from them, we'll make sure to get back to you.

Thanks for your patience, everyone!

Hello,

until recently i had used dropbox on my mobile phone to synchronize pictures. Now I noticed that the app was no longer connected and I had to log in again. Whenever I try to do this I get the error message "Error logging in. Unknown error. Please contact the dropbox support." Username and password are correct. Reinstalling the app didn't help either. In the account I also deleted the device link, so it shouldn't be because of the device limit.
Which other possibilities could be the cause of the error?
Thanks for your help.

Hey there TheIan, thanks for reaching out to us here!

I've just moved your post here as it seems that you're having the same issue as the OP.

Since you've already checked that you're not over the 3 device limit for Basic plans, I'd suggest checking that you're running the latest versions of your device's OS and the mobile app.

I'd just like to note that our team is indeed aware of this issue and are looking into this further, so we will keep you up to date with any news we receive in this thread here.

Let me know if you have any questions!

Hi,
I have downloaded the app from google play but get the above error despite logging in with correct details and with the code delivered to my mobile phone why?

I am always getting an error on my android htc whenever i try to login to the dropbox app. What could be the issue and how do i work around it?
The error is Sign-in Failed, Unknown error, please contact support.
